Abstract
A messaging system includes a messaging platform storing a message from a calling party, a switching mechanism for receiving a call from a subscriber to access the stored message, and a routing application at a server. The subscriber accesses the message at the messaging platform and signals for a callback connection with the calling party. In response, the messaging platform sends bookmark information to the routing application describing a current state of the messaging platform with regard to the subscriber. The routing application directs the switching mechanism to disconnect the subscriber from the messaging platform and connect the subscriber to the calling party. When the callback connection is completed, the routing application directs that the subscriber be re-connected with the messaging platform and sends the stored bookmark information back to same. The messaging platform employs such bookmark information to re-establish the current state.
